3R
Artifact R
Tap: Add RR
At the beginning of each players upkeep that player may put a doom counter on ~ or remove a doom counter from it. Then if it has 3 or more doom counters on it sacrifice ~. When you do, it deals 6 damage to each creature.

A mana rock that you or your opponents can make go BOOM.

Seems like it could be good in the decks that use a lot of the Stuffy Doll-esque effects.

Very unique, exceptionally flavorful, and it creates a lot of tension around the board. Interestingly, in multiplayer you may not even get a say in the doom at all which will make it too fast in some instances for some players to do anything about.

And in terms of politics, that last player is going to be the one who catches all the blame. Hahaha I love it.

Fun card, does nothing if you're ahead since your opponents will just band together and stack the doom counters to get rid of this before you can untap, but if an opponent's ahead he will be wary of nuking his own board just to deny you mana, and even if he does tries to do that, you can make some deals with the table if you reall need that RR. Red also has strong artifact matters cards, so this can be abused. Could see myself running this in Daretti, Scrap Savant, but overall it's nothing exceptionally strong.
